TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5255 SUBJECT: GRB 060614: Swift/UVOT Observations DATE: 06/06/14 19:16:39 GMT FROM: Stephen Holland at USRA/NASA/GSFC/SSC GRB 060614: Swift/UVOT Observations S. T. Holland (NASA/GSFC & USRA) reports on behalf of the Swift/UVOT team: The Swift/UVOT began observing the field of GRB 060614 at 12:45:29 on 2006-06-14, 101 s after the BAT trigger (Parsons et al., GCN Circular 5252). An optical counterpart was detected in the White filter (160-650 nm) at a position (RA,Dec) = (21:23:32.08, -53:01:36.2) (J2000) with a 90% confidence interval of 0.56 arcsec. The optical afterglow was detected in the White, V, B, U, UVW1, UVM2, and UVW2 filters. The detection in all of the UVOT bands suggests that the redshift is less than approximately 1.1. The photometry results are given for the UVOT filters below: Filter T_mid(s) Exposure(s) Mag Err V 5753 189 19.54 0.30 B 5143 196 19.91 0.21 U 4937 193 18.81 0.14 UVW1 4730 189 18.35 0.17 UVM2 5959 193 18.06 0.23 UVW2 5552 195 18.26 0.17 White 147 92 18.30 0.14 The values quoted above are not corrected for the expected Galactic extinction of E_{B-V}=0.02 (Schlegel et al. 1998). / \ /
